Nikolay [14]

Answer:

The quality of a formed rivet is determined by the geometry from its formation of the river heat, and the extent to which the hole is filled up by the rivet.

Explanation:

The quality of a formed rivet is determined by the geometry from its formation of the river heat, and the extent to which the hole is filled up by the rivet. This helps determine the squeeze force, rivet length, rivet diameter tolerance, hole countersunk depth and hole diameter tolerance, plays a big role on the quality of rivet formed. When the tolerance of the hole it’s placed is smaller the grip from the river is stronger unlike when it’s loose.

A ball rolls at a speed of 6cm/s. How far does the ball roll in 40 seconds ? ____cm
sesenic [268]

Answer:

240cm

Explanation:

Speed = 6cm/s

Time = 40 seconds

Speed= distance/time

6cm/s = distance/40seconds

Distance = 6×40

Distance = 240cm

Hence, in 40 seconds, the ball must have rolled the distance of 240cm

An airplane flies 1,592 miles east from phoenix, Arizona, to Atlanta, Georgia, in 3.68 hours. What is the average velocity of th
KiRa [710]

Answer:

433 mph

Explanation:

We know that

Velocity =\frac{Distance}{Time }...Eq(1)

Here,

Distance =1,592 miles

Time=3.68 hours

Putting the value of distance and Time in the Eq(1)  We get

Velocity =\frac{1592\ miles}{3.68\ hours}

Velocity = 432.608\  mph\\Velocity = 433 mph

therefore Average velocity is 433 mph
